Missandei - Game of Thrones

A slave who served as an interpreter to the masters of Astapor, Missandei was freed when Daenerys Targaryen took the Unsullied army and used it to overthrow the slavers. Missandei now serves Daenerys as her trusted advisor and handmaiden. Missandei was born on the island of Naath in the Summer Sea, off the coast of the continent of Sothoryos. She was enslaved at a young age and taken to Slaver's Bay in Essos, where she was eventually put to work as an interpreter for the slaver-master Kraznys mo Nakloz, one of the Good Masters of Astapor.
